West Covina
A city built almost all at once
West Covina incorporated in 1923 but stayed small until after World War II. Then the building boom hit: the population jumped from about 4,500 in 1950 to more than 50,000 by 1960. Entire neighborhoods of single-family homes went up within a few years of each other.
That history matters for main lines. When so many homes are built at the same time with the same materials, their pipes tend to wear out on a similar schedule. Many West Covina lines are now well past the age where repeat leaks and low pressure become common.

Local problems
Typical issues in West Covina
Post-war lines wearing out
Homes from the 1950s boom often still have original pipe nearing the end of its life.
Galvanized steel
Steel supply lines from that era narrow with rust and cause whole-house pressure loss.

Planning the job
Planning a West Covina line replacement
Because so many West Covina homes went up during the same decade, we often see neighbors replace their lines within a few years of each other. If the house next door has already had theirs done, that is a useful hint about the age and material of yours.
Most of these lots are flat to gently sloped, which keeps trenching manageable. The bigger variable is what has been added on top of the line since the 1950s: driveways widened, patios poured, and pools put in. Permits for the work go through the City of West Covina.
If your provider has already told you the leak is on your side of the meter, mention that when you call so we can start with the homeowner line right away.

West Covina water line questions
Which water company should I call about my meter?
It depends on your address. Suburban Water Systems, Valencia Heights Water Company and Walnut Valley Water District all serve parts of West Covina. Your bill names your provider.
My home was built in the 1950s. Is the main line original?
Often, yes. Unless it has been replaced, a home from that era may still have its first line, and it may be galvanized steel.
Can you replace a line under a driveway?
We can, but rerouting the new line around the driveway is often simpler. We look at both options and explain the trade-off.
